①Ready to start up: Northeast Feed Machinery

When the operator is ready to start the machine, he must confirm the storage of each silo and the residual status of each process, understand the machine status and production plan, open each steam trap valve, about two minutes, let off the condensed water in the steam, the startup can be more smoothly.

②Start the granulator:

When the switch of the main engine is pressed, the granulator starts to run, but at this time, the granulator has not really started up, and neither granulation nor oil can be added to wash the mold. After the star-delta conversion of the main motor of the granulator, the ammeter After showing that the current is normal, you should put in some oily materials first, and rinse the ring die for about two minutes to heat the ring die. It is very necessary to heat up the ring die. At the beginning of the feeding, the feeding amount should not exceed 20% of the production capacity of the granulator. Prevent the granulator from feeding too much material in an instant, and the load is suddenly increased, causing machine blockage or equipment damage. When the material is quenched and tempered, it feels tight and can form a mass, and when it can disperse after letting go, close the feed door at this time and proceed to granulation. Observe whether the current of the main engine is stable, and adjust the feeding amount and steam addition amount according to the production performance and current load of the granulator. The feeding amount must be gradually adjusted from low speed to high speed, and the amount of steam added should be adjusted according to the dry humidity of the material. The granulator should avoid overloading, which can easily lead to the rupture of the ring die and the damage of the granulator. Don't be careless and impatient when using a new mold. It is necessary to run in moderately before the new mold reaches the best production capacity.
